If translated into the working of the human brain, we propose that the index layer might be realized by the medial temporal lobe (MTL) and the representation layer might be part of the posterior hot zone, which, as it has been argued, is the minimal neural substrate essential for conscious perception [1]}. In conjunction with working memory,
one might also relate it to the prefrontal parietal network (PPN), [2]}, and the global workspace [3]}, [4]}. As these authors argue,
both are candidates for foundations of consciousness, as well.
